Using the particle in the 1-D box model, estimate the first 4
energy levels of the π-network in hexatriene, C6H8
(H2C=CH–CH=CH–CH=CH2). To calculate the box length, assume that the
molecule is linear and use the values 135 and 154 pm for the C=C
and C–C bonds, respectively. Only 2 out of the 6 ‘π-electrons’ of
the 6 C-atoms can occupy each energy level (Pauli exclusion
principle). Ignore the rest of the electrons (forming the core and
the ??-bonding network). Sketch...
